DEBIAN-CVE-2024-49874

In the Linux kernel, the following vulnerability has been resolved: i3c: master: svc: Fix use after free vulnerability in svci3cmaster Driver Due to Race Condition In the svci3cmasterprobe function, &master->hjwork is bound with svci3cmasterhjwork, &master->ibiwork is bound with svci3cmasteribiwork. And svci3cmasteribiwork can start the hjwork, svci3cmasterirqhandler can start the ibiwork. If we remove the module which will call svci3cmasterremove to make cleanup, it will free master->base through i3cmasterunregister while the work mentioned above will be used. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | svci3cmasterhjwork svci3cmasterremove | i3cmasterunregister(&master->base)| deviceunregister(&master->dev) | devicerelease | //free master->base | | i3cmasterdodaa(&master->base) | //use master->base Fix it by ensuring that the work is canceled before proceeding with the cleanup in svci3cmaster_remove.
